Application: kmail (1.13.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I tried several times to select an email signed with a digital certificate, but the message could not be displayed on the preview panel. Rather, Kmail froze and I had to kill and restart the application. In the last attempt, Kmail crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
